Whether at home or at work: regular airing is important and
keeps you healthy! Build your personal air quality meter!
First of all, use the soldering iron: fit the circuit board with the
air sensor and all other components. Then simply install it in
the housing, calibrate the sensor and the air quality meter is
ready to go. In a well-ventilated room, the green light should
be on. If the air quality drops, the signal light changes to
yellow, indicating that you should ventilate. The highest
warning level is indicated by a flashing red light. This helps
you avoid „thick air“ and its effects like headaches, fatigue
or increased risk of infection. The sensor in this kit reacts to
all combustible gases such as hydrogen, methane, solvent
vapours and many more. Even a direct breathing on the sensor
triggers a reaction. An ideal aid in closed rooms with many
people – you always ventilate in good time! You will need:
